Our blog post on September 23, 2009 was an update of a 2007 article we did in RISK on the relationship between credit default swap quotes and modern reduced form default probabilities. This post illustrates how the probability of government bailouts causes the potential losses of different liability holders to diverge sharply. A similar kind of division can be seen in the trends of default probabilities and credit default swaps. We illustrate this process using the cases of FNMA and Citigroup.

Our April 19, 2009 blog post “Modeling Default for Credit Portfolio Management and CDO Valuation: A Menu of Alternatives” outlined a number of different ways in which one can model default among many counterparties, from retail to corporate to sovereigns, in a correlated way. The most modern technology for doing this is the reduced form modeling technique first introduced by Robert Jarrow and Stuart Turnbull in 1995. This blog provides a simple worked example of how to simulate default probabilities forward in a correlated way using two counterparties and three macro factors.
